Definitions

  • valves are known and used in or for a variety of products. Such valves are often employed in inflatable objects such as inflatable dunnage bags.
  • Inflatable dunnage bags are commonly used to stabilize cargo during transportation of cargo containers (such as railroad cars and semitrailers), thereby improving safety and reducing the likelihood of damage to the cargo.
  • Dunnage bags are commonly inflated and deflated before and after use through valves configured for this purpose.
  • Dunnage bags are typically positioned in voids or spaces between the cargo and/or between the cargo and the walls of the cargo container and inflated to a desired internal pressure, such as a designated operating pressure.
  • the user typically positions the dunnage bag in the appropriate void or space and then inflates the dunnage bag to the desired internal pressure using pressurized gas such as air from a pressurized gas supply.
  • pressurized gas such as air from a pressurized gas supply.
  • the user connects the pressurized gas supply to the valve, which is attached to the inflatable/deflatable body of the dunnage bag and which provides an opening in the dunnage bag. If the dunnage bag needs to be repositioned during inflation, the user opens the valve associated with the dunnage bag to enable the gas from within the dunnage bag to escape, partially deflating the dunnage bag.
  • the user then closes or enables the valve to close and the dunnage bag can be repositioned and inflated to the desired internal pressure, such as the designated operating pressure.
  • the desired internal pressure such as the designated operating pressure.
  • valves There is a continuing need to make such valves simpler, easier to manufacture and assemble, made from or with less components, less expensive, more durable (e.g., reusable for longer durations), and that provide relatively greater gas flow rates into and out of the inflatable object.
  • Various embodiments of the present disclosure provide a reusable valve that is simpler, easier to manufacture and assemble, made from or with less components, less expensive, more durable (e.g., reusable for longer durations), and that provides relatively high gas flow rates through the valve into and out of an inflatable object (such as a dunnage bag) to which it is attached.

Description

INFLATION VALVE
BACKGROUND
[0001 ] Various pneumatic valves are known and used in or for a variety of products. Such valves are often employed in inflatable objects such as inflatable dunnage bags.
[0002] Inflatable dunnage bags are commonly used to stabilize cargo during transportation of cargo containers (such as railroad cars and semitrailers), thereby improving safety and reducing the likelihood of damage to the cargo. Dunnage bags are commonly inflated and deflated before and after use through valves configured for this purpose. Dunnage bags are typically positioned in voids or spaces between the cargo and/or between the cargo and the walls of the cargo container and inflated to a desired internal pressure, such as a designated operating pressure.
[0003] More specifically, the user typically positions the dunnage bag in the appropriate void or space and then inflates the dunnage bag to the desired internal pressure using pressurized gas such as air from a pressurized gas supply. Typically, to inflate a dunnage bag, the user connects the pressurized gas supply to the valve, which is attached to the inflatable/deflatable body of the dunnage bag and which provides an opening in the dunnage bag. If the dunnage bag needs to be repositioned during inflation, the user opens the valve associated with the dunnage bag to enable the gas from within the dunnage bag to escape, partially deflating the dunnage bag. The user then closes or enables the valve to close and the dunnage bag can be repositioned and inflated to the desired internal pressure, such as the designated operating pressure. When the dunnage bag needs to be removed from its position between the cargo or between the cargo and the walls of the cargo container to enable the cargo to be unloaded from the cargo container, the user opens the valve to enable the gas in the dunnage bag to escape and thus deflate the dunnage bag.
[0004] There is a continuing need to make such valves simpler, easier to manufacture and assemble, made from or with less components, less expensive, more durable (e.g., reusable for longer durations), and that provide relatively greater gas flow rates into and out of the inflatable object.
[0005] Accordingly, there is a need for a new and improved valve that solves these requirements, and for new and improved inflatable objects such as dunnage bags having such new and improved valves.
SUMMARY
[0006] Various embodiments of the present disclosure provide a reusable valve that is simpler, easier to manufacture and assemble, made from or with less components, less expensive, more durable (e.g., reusable for longer durations), and that provides relatively high gas flow rates through the valve into and out of an inflatable object (such as a dunnage bag) to which it is attached. More specifically, various embodiments of the present disclosure provide a valve for that can be used in connection with any suitable inflatable object such as, but not limited to: a dunnage bag, a bag other than a dunnage bag, an air mattress, an inflatable boat or floatable object such as a raft, and a tire.
[0007] In various embodiments, the valve generally includes: (a) a housing defining a gas passageway and configured to be attached to an inflatable object; and (b) a sealing assembly connected to and moveable relative to the housing, and configured to be in: (i) any one of a plurality of resting closed positions to prevent a gas such as air from passing through the housing, and (ii) any one of a plurality of different open positions that enable gas such as air to pass through the housing.
[0008] In various embodiments, a cap assembly may be connected to the housing to cover one end of the housing to protect the gas passageway of the housing from contaminants.
[0009] In various embodiments, the housing includes a cylindrical wall having opposing outer and inner surfaces, wherein the inner surface partially defines a gas passageway. The housing further includes, among other elements described below, a stem supporter integrally connected to and extending inwardly transversely from the inner surface of the cylindrical wall. The stem supporter is configured to support the sealing assembly, enable the sealing assembly to move relative to the housing, enable the sealing assembly to be positioned in the open and closed positions, and define relatively large gas passageways through the housing.
[0010] In various embodiments, the sealing assembly includes a stem, a somewhat flexible compressible sealing ring attachable to the stem, a sealing plate attachable to the stem, a spring positionable on the stem, and a locking pin positionable in and lockable into the stem.

DETAILED DESCRIPTION
[0038] Various embodiments of the present disclosure provide a valve, and particularly a valve for an inflatable object. It should be appreciated that the valve of the present disclosure can be used in connection with any suitable inflatable object such as, but not limited to: a dunnage bag, a bag other than a dunnage bag, and air mattress, a raft or other inflatable boat or floatable object, and a tire.
[0039] Referring now to the drawings, Figures 1 to 23 illustrate one example embodiment of the valve of the present disclosure, which is generally indicated by numeral 100. In this illustrated example embodiment, the valve 100 generally includes: (a) a housing 110 defining a gas passageway 190, and configured to be attached to an inflatable object (not shown) such as a dunnage bag (not shown); and (b) a sealing assembly 200 connected to and moveable relative to the housing 110, and configured to be in: (i) any one of a plurality of different closed resting positions (such as shown in Figures 2 and 3A) to prevent a gas such as air from passing through the housing 110, and (ii) any one of a plurality of different open positions (such as shown in Figure 3B) to enable gas such as air to pass through the housing 110.
[0040] In this illustrated example embodiment, the housing 110 (as shown in Figures 1 to 8) is formed from a one piece molded plastic body. In this illustrated example embodiment, the housing 110 generally includes: (a) a cylindrical wall 112; (b) a cylindrical locking lip 120; (c) a cylindrical or partially cylindrical annular ring 126; (d) a cylindrical or partially cylindrical attachment flange 130; (e) a cylindrical sealing seat 150; and (f) a stem supporter 160.
[0041 ] More specifically, the cylindrical wall 112 of the housing 110 has opposing outer and inner surfaces 114 and 116. The inner surface 114 partially defines the gas passageway 190 of the housing 110.
[0042] The locking lip 120 of the housing 110 is cylindrical and is integrally connected to and extends outwardly or transversely from the outer surface 114 of the cylindrical wall 112 of the housing 110. The locking lip 120 is configured to be engaged by a suitable cap (not shown). In certain alternative embodiments that are not shown, the locking lip does not extend all the way around the cylindrical wall 112. In certain alternative embodiments that are not shown, the locking lip is provided in two or more sections extending outwardly transversely from the cylindrical wall 112. In certain alternative embodiments that are not shown, the housing does not include any locking lip.
[0043] The annular ring 126 of the housing 110 is cylindrical and is integrally connected to and extends outwardly transversely from the outer surface 114 of the cylindrical wall 112 of the housing 110. The annular ring 126 is configured to assist in securing the valve 100 to a wall (not shown) of an inflatable object (not shown) such as a dunnage bag (not shown). In certain alternative embodiments that are not shown, the annular ring does not extend all the way around the cylindrical wall 112. In certain alternative embodiments that are not shown, the annular ring is provided in two or more sections extending outwardly transversely from the cylindrical wall 112.
[0044] The attachment flange 130 of the housing 110 is cylindrical and is integrally connected to and extends outwardly or transversely from the outer surface 114 of the cylindrical wall 112. The attachment flange 130 has opposing first and second surfaces 132 and 134. The attachment flange 130 of the housing 110 is configured to be positioned such that surface 132 of the attachment flange 130 engages an inner surface (not shown) of a wall (not shown) of an inflatable object (not shown) when the valve 100 is attached to that inflatable object. Thus, the portions of the housing 110 extending from surface 134 of the flange 130 are configured to be positioned inside the inflatable object, and the portions of the housing 110 extending from surface 132 of the flange 130 are configured to be positioned outside of the inflatable object. The attachment flange 130 is thus configured to co-act with the annular ring 126 to assist in securing the valve 100 to a wall (not shown) of an inflatable object (not shown) such as a dunnage bag (not shown). In certain alternative embodiments that are not shown, the flange does not extend around the entire housing. In certain alternative embodiments that are not shown, the flange is provided in two or more sections.
[0045] Although not shown, the housing can alternatively include a standoff configured to prevent another wall (not shown) of an inflatable object (not shown) from sealing itself to the portion of the valve 100 that is inside of that inflatable object when the valve 100 is attached to that inflatable object, thereby facilitating easier deflation of that inflatable object.
[0046] The sealing seat 150 of the housing 110 is generally cylindrical and is integrally connected to and extends downwardly from the second surface 134 of the flange 150. The sealing seat 150 is configured to be engaged by, mate with, and to provide a seat that is engaged by the sealing assembly 200 (as further discussed below) to close or seal the valve 100 or the passageway 190 defined by the housing 110 of the valve 100.
[0047] The sealing seat 150 is configured to be engaged by the sealing surface of a somewhat flexible compressible sealing ring 230 (described below) as generally shown in Figures 2 and 3A to create the seal between the sealing assembly 200 and the housing 110 when the sealing assembly 200 is in any one of the closed resting positions as shown in Figures 2 and 3A and as further discussed below.
[0048] The stem supporter 160 of the housing 110 is integrally connected to and extends inwardly transversely from the inner surface 116 of the cylindrical wall 112 of the housing 110. As best shown in Figure 6, the stem supporter 160 includes an outer ring 162, a plurality of and particularly three spaced apart connecting arms 164, 166, and 168, and an inner ring 170. The outer ring 162 of the stem supporter 160 is integrally connected to and extends inwardly transversely from the inner surface 116 of the cylindrical wall 112. The spaced apart connecting arms 164, 166, and 168 are integrally connected to and extend inwardly transversely from the outer ring 162. The inner ring 170 is integrally connected to each of and extends inwardly transversely from each of the three spaced apart connecting arms 164, 166, and 168. The inner ring 170 defines a central stem receiving opening 176 configured such that the shaft 220 of the stem 202 (described below) is axially moveable through the stem supporter 160 as further discussed below.
[0049] It should be appreciated that the spaced apart connecting arms 164, 166, and 168 and the inner ring 170 define three spaced apart relatively large gas passage openings 190a, 190b, and 190c that also partially define the passageway 190 of the housing 110. These spaced apart relatively large gas passage openings 190a, 190b, and 190c enable a significant amount of gas to pass though the housing 110 and thus the valve 100 when the sealing assembly 200 is in any one of the open positions during inflation or deflation (through the valve 100) of the inflatable object to which the valve 100 is attached. The stem supporter 160 is thus configured to: (a) support the sealing assembly 200; (b) enable the sealing assembly 200 to move relative to the housing 110; (c) enable the sealing assembly 200 to be positioned in any one of the closed resting positions and any one of the open positions; and (d) enable gas to pass through the housing 110.
[0050] In this illustrated embodiment, the housing 110 is one piece and molded from a plastic such as polyethylene. It should be appreciated that the housing can be made from other suitable materials, made in other suitable manners, and made from two or more connectable pieces in accordance with the present disclosure. It should be appreciated that the one or more of the components of the housing can be alternatively configured in accordance with the present disclosure. For example, the number or positions of the spaced apart connecting arms and the openings that they partially define may vary in accordance with the present disclosure. [0051 ] In this illustrated example embodiment, the sealing assembly 200 (as shown in Figures 1 , 2, 3A, 3B, 4, and 9 to 23) is formed from five connectable or connected components and specifically includes: (a) a stem 202; (b) a flexible compressible sealing ring 240 positioned in and connectable or attachable to the stem 202; (c) a sealing plate 250 positionable on and connectable or attachable to the stem 202 to maintain the flexible compressible sealing ring 240 on or connected to the stem 202; (d) a spring 270; and (e) a locking pin 280 positionable in and lockably connectable into the stem 202 to maintain the entire sealing assembly 200 connected to the housing 110 and to facilitate operation of the sealing assembly 200 and the entire valve 100 as further discussed below.
[0052] More specifically, in this illustrated example embodiment, the stem 202 (as shown in Figures 1 , 2, 3A, 3B, 4, 9, 10, 11 , 12, and 13) is formed from a one piece molded plastic body. The stem 202 generally includes: (a) a base 204; and (b) a shaft 220 including a lower portion 221 and a locking pin receiver 222.
[0053] The base 204 of the stem 202 is generally cylindrical and has a first or bottom side 205 and an opposite second or top side 206. The base 204 includes an upwardly extending cylindrical first or outer ring or rim 207 and an upwardly extending cylindrical second or inner ring 208.
